Abstract: Des stations portatives munies d'un seul récepteur permettant la communication en utilisant une pluralité d'intervalles par trame lors de la transmission multiplex temporel asynchrone (TDMA). Lors de la communication entre une des stations portatives et une station cellulaire des signaux de deux canaux de 32 kbps, qu'un échangeur convertit en un canal de 64 kbps, la station portative occupe deux intervalles d'une trame TDMA. Un contrôleur de la station cellulaire répartit ces deux intervalles de manière à les séparer l'un de l'autre d'au moins un intervalle.  Alternativement, le contrôleur les place en position adjacente l'un à l'autre et leur attribue la même fréquence porteuse. De telle manière, la communication à un taux de transmission de 63 kbps peut s'effectuer par l'emploi de deux intervalles ou deux canaux de 32 kbps.

Abstract: ABSTRACT    A size press arrangement  including a  first roll mounted rigidly on a frame of the size press and a second roll which forms a size-press nip with the first roll.  The second roll is mounted at a level higher than the level of the first roll and,  on a loading arm that is supported pivotally on a transverse shaft on the frame of the size press.  The loading arm is pivoted by loading cylinders so as to produce a desired pressure level in the nip and to open the nip for threading of the web and for replacement of rolls.  The paper web is passed into the nip as guided by a guide roll and out of the nip over a spreader roll or an air-turning device.  The rolls that form the size-press nip are arranged in relation to one another such that the nip plane passing through the rolls  forms  an  angle  of  from  about  35° to  about  120°, advantageously from about 50° to about 60°, preferably 55°, in relation to the horizontal plane.  The web is passed into the nip at an angle of substantially about 90° in relation to the nip plane and to be passed out of the nip at an angle of about 90° ? 7° in relation to the nip plane.

Title: Method and device for the separation of a contaminated top layer
Inventor: VAN SCHIE LOUIS
IPC: B01D17/028
Filed: 1994-02-16
Abstract: For the separation of a contaminated floating top layer of oil or oil substances, a continuous laminar flow is created on or near the surface, in order to achieve a high efficiency. The special feature of this is that the optimum separation of the contaminated oil liquid is achieved by creating a drop in the level of the liquid to be cleaned as it passes from the inflow area to the discharge area, after separation has occurred. The creation of this is controlled by a number of parameters, such as the flow, the thickness of the layer, etc. and, furthermore, by placing a number of baffles (8 8') in the path of the flowing liquid (V) as it moves through a tank (1).  The total amount of liquid flowing through the tank (1) is now adjusted in such a way that the correct control of the upper laminar flow (S) and the dominant more turbulent lower flow near the bottom (9) of the tank (1) produces a controllable constant difference in height (.delta.h). This total difference in height (.delta.h) can also be attained by cascade operation.

Patent CA-2121896-A1 (CA)
Inventor: DAVIS ANDREW GORDON
IPC: H04M11/06
Filed: 1992-11-13
Abstract: A digital coder receives (input 100) either speech or voice-band data. When receiving speech this is coded by a digital speech coder (102) formatted into frames with parity bits (106). If modulated data are present this is recognized by a detector (107) which routes the signals instead via a demodulator (108). Parity bits are generated from the same frame portions but parity is inverted (110) so that a parity checking unit at a receiver (not shown) can readily recognize the change. Preferably means (111) are provided to insert into data frames codewords identifying the start and end and indicating the type of modulation in use. Additional detectors (107) and demodulators can be added for different types of modulation.

IPC: F23R3/26
Filed: 1994-12-08
Abstract: In the operation of gas turbine engines, it is an ever increasing goal to reduce the amount of harmful elements contained within the emissions of the engine. In particular, it is of primary importance to reduce the amounts of nitrogen oxides contained within the emissions.  The use of a catalytic combustor is one known means by which the formation of nitrogen oxides may be controlled.  However, the use of a catalytic combustor in a gas turbine engine has been known to be effective primarily in the upper ranges of engine operation.  The present invention provides a combustor arrangement for a gas turbine engine that employs a first combustor means that utilizes a catalytic bed to react a mixture of fuel and air during an upper range of engine operation and a second combustor means that utilizes a plurality of premixed fuel injectors to ignite a mixture of fuel and air during a lower range of engine operation.

Abstract: An improved method for the safe transportation and handling of hydrogen fluoride from a point of origin to a desired destination. The method involves adding, at the point of origin, a sulfone, having the general formula R-SO2-R' wherein R and R' are monovalent hydrocarbon alkyl or aryl substituents containing from 1 to 8 carbon atoms, to hydrogen fluoride to form a mixture containing an amount of water of no more than 30 weight percent of the total weight of the hydrogen fluoride in the mixture. The mixture also includes a weight ratio of sulfone to hydrogen fluoride in the range of from 1:100 to 100:1. The mixture is then transported to the desired destination. At the desired destination, the mixture is separated into a sulfone phase, comprising sulfone and containing less than 20 weight percent hydrogen fluoride based on the total weight of the sulfone phase, and a hydrogen fluoride phase comprising hydrogen fluoride and containing a weight ratio of sulfone to hydrogen fluoride of less than 2:100. The sulfone phase is then returned to the point of origin to reuse as sulfone.

IPC: G01B11/27
Filed: 1995-05-31
Abstract: The locating of the local centre of rotation of a cylindrical body from outside the body, while the body is rotating upon supporting bearings is carried out using a number of distance-measuring diode lasers mounted upon a movable chassis. Such determination of local centres of rotation can be used in the case of hot kilns to re-align the supporting sets of bearings upon which the kiln is rotatably supported. The integrated triangulation monitoring chassis is located in sequence at respective axial stations located along the kiln, adjacent the supporting bearings, and at each station a simultaneous single set of readings from three diode lasers to the shell surface enables a computer to calculate the location of the centre of rotation relative to the chassis. The location of the chassis, relative to a selected datum, is determined by the use of an integrated total station theodolite, which is repositioned, as required, to enable it to access and locate the chassis. A pair of prism reflectors mounted to the chassis facilitate the action of the theodolite, remote radio control being used to align the respective prisms towards the theodolite, in reflecting relation therewith. With each relocation of the theodolite datum its location relative to the original datum is determined, so that the derived centre distances, as measured by the diode lasers, can be plotted in true relation with a common datum, enabling ready determination of the corrections to the supporting bearings that are necessary, in order to achieve a unified axis of rotation for the kiln.
